"The Sister"...........

Starts with 7.

I was looking for a fast 7mm when I got an offer I couldn't refuse. So, while a 7mm STW was (and still is) my main goal, this gal will do until then.

Remington 700 SPS Stainless in 7mm Remington Ultra Mag

I ordered an EGW 20 MOA Pic Base and mounted a Leupold MK4 4.5-14x50 in Leupold MK4 Rings on top of her. Put a Timney Trigger set to 2.25 lbs inside her and took her to play.

This is the rifle I referenced in the thread about the factory barrel test fire. Took me forever to clean her up from the factory. Later on at the range, I still had the copper fouling problem. This barrel soaks up copper fouling like a sponge!

Anyway, the offer I had was a gift of almost 200 rounds of handloaded ammunition in 7mm Ultra Mag. Well, I couldn't pass that up. So, I went looking for a rifle to shoot it in and found this one new in the box.

The gift of ammo.

139gr SST / 162gr SST / 160gr Partition

7mmRUMLoads.jpg

I had originally planned to pull all the 139gr SST bullets and use the brass to load 162gr A-Max bullets. But at the range, while testing velocities..........the 162gr SST loads were attrocious (110 SD) and the 139gr SST and 160gr Partition were pretty consistent. Therefore, I will be pulling all the 162gr SST bullets and using the brass for something else.

By the way, I fault the powder used in the 162gr SST loads (AA8700) and NOT the bullets. I'll do something else with the bullets. The powder will entertain the kids on the driveway. Retumbo was used in the 160gr Partition loads and it had the most consistent velocity.

Recoil was abrupt but not painful. But (VIDEO)............

......boy howdy.......what a ball of fire!!!! The photobucket minimized version doesn't do the original version any justice.

Anyway, this range trip was just to try the recoil with the factory stock and see the consistency and velocity of the factory loads.

I will be ditching the factory stock and it's short length of pull (even for a Carney), crappy fit/finish, zero bedding, and barrel pressure point. By the way, I figure if I'm going to hack on Savage for the cruddy fit/finish on their stock...............might as well ding Remington for the same thing while I'm at it.

7mmRUMinFactoryStock15.jpg

Pathetic!

I am actually going to try a Choate stock with aluminum V-Block for this rifle.

That way, I can also use the stock for my future plans involving this rifle.

Anyway, back at the ranch with a fired case.............I was trying to measure the ogive length to lands with a 162gr A-Max. Unfortunately, Remington puts 10mm of freebore in the 7mm Ultra Mag to reduce pressure. Unfortunately, this is not conducive to accuracy with shorter bullets. Unfortunately again, with the excessive freebore, I can't even touch the lands with the 162gr A-Max!!!!!

139gr SST / 162gr SST / 162gr A-Max (seated long)

7mmRUMLoads9.jpg

Therefore, I will also be trying the 180gr Berger Hunting VLD in this rifle. Trying to get closer to the lands with the longer bullet. But, still unable to touch them!!!

160gr Partition / 180gr Berger

7mmRUMLoads11.jpg

I will test the accuracy of the A-Max and Berger.......

7mmRUMLoads5.jpg

.........and use the winner to make 100 rounds of ammunition (found a deal on 40 new cases as well). The other 100 or so will be the 139gr SST and 160gr Partition.

My long term goal for this rifle is to shoot the barrel out with the brass I have. I figure that to be around 600-800 rounds. Once I do that, I will rebarrel the rifle in 7mm STW with a 30" stainless Krieger or Lilja Varmint Contour and 1-8" twist. That..........is the future of this rifle.

For now, I will shelve this girl and wait for the Choate stock. Once I have the stock, I will start load developement with the A-Max and Berger. After that, she will be my long range medium game rifle until I toast the barrel.

Why do I call her "The Sister", you might ask? Well............wait 'til you see, the "OTHER Sister"..............

    Sweet. That freebore is crazy!

    Can't wait to see the sister.

    Yes, some stupid crazy freebore. But, it's designed to act as a gas expansion chamber, maximizing velocity due to a longer pressure curve. Without it, you'd have dangerous pressures as often experienced with custom "short throated" chambers.

    Oh, and you mean, the "Other Sister".

    The recoil lifted the front rest off of the bench:yikes:

    I wasn't after groups that day, so I used the "light" rest. But yes, the recoil is rather...........sudden and vigorous.

    Think you got enough barrel there, Butch?

    Hehehe. Wait till you have some heavy bullets on top of that case!

    If you are going to shoot the barrel till it is useless, when are you going to put a brake on it?

    Meh, unlike some.....who are afraid to put a gun to their shoulder..........I don't mind recoil.

    :tooth:

    Besides, the Choate stock (at 3.5lbs) will dampen the recoil a little bit. At least not make it so sudden, with the added mass.

    ...That way you get a bit more time to anticipate impact.

    Looking forward to 30+ round strings from the prone position videoed :)
    With the original stock that is.

    That alone, would cook my barrel!!!!! Nope. Not afraid of the recoil, but it's fire a round and cool the barrel.........fire a round and cool the barrel.......for 4 rounds and then cleaning for this gun. From all research, this method is the secret to barrel life beyond 450 rounds.

    I'd at least like the barrel to outlast my brass. Get my money's worth, ya know.

    Yep. A 3 shot group is about all you get before cooling time.

    That's how many firings the brass will go, before it needs annealed, too.

    In this heat, I can't even make a 3rd shot before the barrel is too hot. So, it's going to be a cool between shots endeavor, most likely.

    Yeah, I'm hoping to get 3 or 4 loadings out of the brass. With 200 cases, that will likely be the life of the barrel if I pace myself.

    And you claim Savage rifles are ugly? Did you SEE that stock on your new Remmington?

    I see past that. I was undressing the rifle in my mind before I even got her home.

    You still should shoot for groups. Nothing fancy, just a few rounds with each load. Then compare them with the new stock.

    Or, I can text you some pictures or me in my spandex shorts and no shirt.

    Your choice, choose wisely.

    Why? Just wasted rounds and life off the barrel for no real reason. I KNOW the stock will make it more accurate. I KNOW bedding the action will help. So, why waste time and effort?

    No, I'm done until the new stock is in place. Go ahead......send the pic.........I ain't skeerd.

    Not worth it. Other than the stock, no more money will go into this rifle. Aside bullets and powder.
